I think if it will only be between Iran and the US, it will not be a full-blown war. Iran will be flexing all her muscles while the US will only lift a finger and we still know which side the tide will favor. This will just become another rape case in the Middle East, a total annihilation against a helpless opponent.
We aren't sure if that will gonna happen since advanced technology is growing vastly, which means there are more advanced weapons that can instantly cause massive destruction. They have allies also, which is Russia and many more that can do that for them when needed.
This is clearly a meaningless war that Trump is creating, but Iran is too weak to fight, even though they have allies, but I think there is no fight from their allies. Russia or any other country will not fight. All did not want to lead to a big war.
I doubt that the people of South-East Asia will join the war because they lack good armies.
Southeast Asia is a peaceful region where there is no war, although they are truly militarily weak
Gonna change the thread subject to "Affection of War to Bitcoin" since it is true that it's very far away to have WWIII.
I have not see a perspective of World War III, it's all just an exaggeration of everyone
